ubject: HIT:CD ROM towers, etc. (part 1) In early December I requested information on hardware configurations,etc., for CDs and networking. I got many wonderful responses. Thank you to all who provided such valuable information on my request. You touched on so many aspects of the situation that I hadn't even become aware of yet. There is really no where else I could have gotten this kind of help in such a short time! This is my first attempt at compiling and posting a hit and I realize I have much to learn. I tried this last night in two parts and got half bounced back because it was too long. Sorry to do that-the part that went through had no explanation attached. So I'll try again in THREE parts! ------- I could use a HIT on this topic of netwoking CD ROMS. From responses to that question asked on other listservs I'm getting the notion that to mirror the CD on a harddrive is cheaper and faster. (It could however encourage unauthorized duplicating) THat may not be possible however if the CD title requires multiple disks, such as the Laserquest Bibliographic/MARC package. ------ The only part of your question I can answer is about CD_ROMs. The fine print on the package will tell you the limitations. Many of the most common are one user only. The networkable ones (like encyclopedias) are very expensive - $1000 for 2-8 users at a time. Some are going to pricing by the number of students in a school which makes more sense to me. I have a 7 bay tower with only 3 bays currently used for a magazine index (InfoTrac). My small network has Follett Unison and InfoTrac running on the same machines. We are in the process of networking the whole district and upgrading my network. I understand that Macs can access my network (I have PCs on Ethernet)if the proper software is installed. Most of the staff wants Macs. I have spent more money on technology than I would like, but I try to keep up the print collection also. There are some items: fiction, history, illustrated books which are better in print and don't go out of date too fast. I try to buy print items which will be useful for a long time. I am interested in hearing other responses. ------- Call Diana Pope at Logicraft. 800-678-1692 We use their towers and network to 1,400 computers simultaneously. Yes, up to 50 users access any of our 70 drives; that means a potential of 3,500 simultaneous users. I love it! Good luck, Phyllis ------- IMHO it would be better to buy a multi-gig memory and load the CDs to the server. With a tower, it is limited to just a few disks and switching in and out. Takes much of your time. But once loaded to the hard drive, it's just punch and run. Also, IMHO, I like the idea of all items on all computers. Provides more access. Good luck! ------ You have many decisions to make on this issue. I too am in the process of installing a CD ROM tower. Here are my thoughts. I would buy the largest capcity CD ROM tower that you can afford. I had found a 14 drive tower for $6,000.00 some time ago, but I have been unable to find the catalog and source in spite of a lot of searching. I do think that the use of CD ROMs will grow before it eventually is replaced with something faster. We plan on having access to the CD ROM from all classrooms. According to what I have heard and read, the capacity of the tower and sytem should take care of the access use. I would not connect the catalog to the same computers as the CD ROMs. Unless you are going to have a lot of computers, it might mean that someone would be unable to access the catalog for quite a while. As to the number of computers, I would suggest at least 15-20. Even more if you can could be used, but don't give up shelf space for it. Books are the heart of a library and will remain so. good luck. Sounds exciting. ------- The first question I have for you is are you using IBM type or MAC type computers. We have an IBM Novell network with 50 stations on our network. We have a CD Server that has 10 CD's which are available at any workstation on the network. We use OPTINET software to run the CD Server. The CD Server is not used as a work station. The students in our High School love the CD stack and it is the most used item on the network. Yes, you should have the CD stack accessable from any station in the school. Our Card Catalog (UNison) is also available from any station and this is very helpful to the students as they can look before coming to the library to see if what they want is available. Our school has about 475 students (grades 9 - 12). We have two labs that are on the network. One writing lab and one technology lab. The business dept uses stand alone computers right now but will probably network one of these days. Our school also uses the OSIRIS attendance and grade program and it is on our network. The CD Rom Server that we have is one that I built myself. By doing it yourself you can add one drive at a time if you are short on budget. The SCSI CD drives are kind of expensive--about $350 to $450 each so you can see if you have 10 drives you have a big investment without the computer. The OPTINET software is about $1,000 for a 100 user license. Novell 4.1 software for schools can be purchased for $995 (100 user license)/ ------- >1.

We have 170 computers in our school all networked. Cost for a tower=$4000 > Combine all... but you will need some standalones. > The LMC should have 2 workstations for your use and circulation (one with a barcode scanner) and at least 12-16 workstations for students (half a class). ------- I have a CD-ROM tower made by Optinet. It has 7 "garages" and I have 2 CD-ROM drives daisy chained to it as well as using the CD in the server, for a total of 10 ports going at once. I'm buying another 7-unit tower next year. I have all the CDs AND the automation program in all 6 stations in the library (that's not NEARLY enough) and the computer lab of 26 computers can also access all the programs at the same time. Yes, multiple computers can be using the same program at the same time, and I do like the system. If you have everything on every station, people don't line up if they all need the same thing. We bought the tower for about $6,000 I think - I'm at home now so I can't be sure. As far as what you buy, I can't advise you on that, but good luck. Mary Helen Fischer, District Librarian Buckeye Union School District Shingle Springs CA jlf@footnet.com Subject: HIT:CD_ROM towers, etc. (part 3) I can tell you our experience. WE have a 6 cd tower networked to all our stations, along with the online catalog. If it is a networkable CD-ROM, more than one person can access it at a time. But if it is multi-media, it really slows it down. So we put our most media intensive CD-ROMs on the hard drive (don't ask me how to do it, our volunteer tech person did it). Anyway, it works well. As for work stations, in our school we started with 2 for 450 students, and now have 12 for 550 students. They can all be busy, but I would think you want at least 6. Hope this helps. -------- >1.

If this is not a good idea, >what is? I like a tower because you load the CD's that you have selected and you don't touch them again (except for updates). Depending on your license, multiple users can access the same cd at the same time with no loss of time or quality. I am intersted in the possibility of down-loading CD's to a giant hard drive because I have heard that access from a hard drive is 20-25 times faster. My tech guys say that the only problem comes when you have to clear the HD and reinstall the updates. You might want to ask about this especially for a large school. Towers cost from 2000-5000 for 7 bays. Most brands are just as good as any other--just don't overbuy-some towers have much more power built=in than you would ever need. You also need linking software from the tower to the server. I think it's called SCSI, but am not sure. At the high school we had 14 CD's available, but I think 7 would be adequate for a Jr high- an encyclopedia with atlas and dictionary, a magazine database, a SIRS product, and one for each curriculum area, like Time Magazine almanac for social science, Magill's Science or an anatomy CD for science, a Gale authors product for English. I wouldn't buy more because you plan to have Internet access and that will provide access to college info, career stuff, news services, biography, etc. (One of my friends now buys on-line access to the Britannica rather than installing it at the library. He says it is trouble-free, and the cost for his school is similar.) > >2. Should we plan to have our automated catalog on the same workstations as >our CDs? Or separate stations for each? Seems logical to me to combine but >I've never worked in that situation. Will we need more or fewer stations if >we combine? We can/will have internet access on any or all stations. Absolutely. With today's tech solutions there is no reason to reserve one station for any single dedicated function. Your vendor can set up a menu screen that shows all the choices, and the student just types the letter or number of his/her choice. We included a word processing program, too. I even had access to every database on the circulation stations because you just never know what you might be doing when you need an answer. Naturally, you don't have circ on the student stations. > >3. How many stations should we have at a minimum? There will be no card >catalog and our print collection will necessarily be small to begin with, >making the demand on electronic resources higher. Is it cost effective to >spend for an additional station or turn that same amount into print materials? My ideal is to have one station for every two students in the average sized class (17 stations for a class of 34). I don't think every kid needs to be conducting research at the same time on the computers if you have designed a good research project. Some will be at the computers, some will be using print, some will be in discussion groups problem-solving with their team. I had 1 station for every three students, and it was usually enough except when the stray student bopped in from a class with a research need. If the classrooms have access, this won't happen to you. Remember that the network version of the CD's are sold with licenses for the number of users. This cost will influence your decision, too, because you have to pay more for a multi-user license will take away funds from hardware and vice versa. The classrooms count as users, too! You will have to have a core of reference materials. But I kept mine short and sweet--about 200 volumes for the high school and four sets of print encyclopedias (1 in Spanish). Best of luck to you. Again, my strong advice is to hire a vendor who knows what he is doing and stick with him! ----- We have a system called MICROTEST DISCPORT PRO. The software runs off the fileserver and the ROM drive are attached to a hub. Each hub will support up to 14 drives I understand. We have two hubs each with 7 drives currently. We will be adding more later and it should be relatively inexpensive to do so, we hope. We combined the electronic catalog and the networked ROM drives. We have standalone ROM drives in a different area. I planned our new facility for 6 computer terminals for each class in the media center. We have 3 pods of 6 computers for the three classes we can seat at the same time. The 6 units for each class is BARELY adequate because of the amount of full-text information we subscribe to as a new school. At my old school we had MAS but not the full-text. Here we the the full-text Elite, as well other full-text ROMs and the seat time really increased. I suppose if I were doing it again I would go for more, although all of those computers take a lot of space. Thanks again to all of you--hope I have time to digest all of this and make some informed decisions before the next issue crops up.
