Retired: 1997 Recommended Specifications for Public Access Work Stations in Federal Depository Libraries

[ Note: These 1997 standards are now superseded. For a complete explanation of LPS' current workstation recommendations and requirements, go HERE. ]


(from Administrative Notes, vol. 18, no. 9 (June 15, 1997)


These recommended specifications are intended to assist depository librarians who are planning purchases of new personal computers (PCs) for public use in Federal depository libraries. The Federal Depository Library Program (FDLP) "Recommended Minimum Specifications For Public Access Work Stations in Federal Depository Libraries" (AdNotes, v. 17, no. 7, May 15, 1996) and "Spatial Data Supplement to Recommended Minimum Specifications For Public Access Work Stations in Federal Depository Libraries" (AdNotes, v. 17, no. 8, June 15, 1996) are both superseded by this document.


Recommended New Work Station Configuration


COMPUTER

Processor
IBM-compatible Pentium chip, 133 MHz minimum. Consider 166Mhz or 200 MHz, and Pentium MMX processors.

Ports
One (1) Serial
One (1) Universal Serial Bus (USB)
One (1) Parallel
One (1) P/S-2 Mouse
One (1) SVGA Video (If video is built into system board.)

I/O bus
PCI/ISA (should have at least four available slots after system is configured for delivery)

Drive Bays
One (1) 3.5" HH.
Three (3) 5.25" HH Externally Accessible.
Two (2) 3.5" HH Internal.

Memory (RAM)
24 MB minimum - 48 MB recommended.

Hard Disk Drive
3.0 gigabytes (Gb) capacity, partitioned into two 1.5 Gb drives for quicker access time
IDE or SCSI interface

Floppy Disk
3.5" 1.44MB drive. Use an older system for floppy conversion.

CD-ROM Drive
4X speed minimum; 8X speed recommended. Single platter or changer design. Should support all available standard CD formats. Avoid proprietary I/O designs.

Monitor
17" Super VGA (SVGA) Multimedia monitor. May want to consider rotatable displays if in a technical services area or if users do a lot of word-processing.

*FOR CARTOGRAPHIC DATA USE: 21" monitor, Super VGA (SVGA) compatible, with at least 70 MHz vertical refresh rate at 1024x768 resolution non-interlaced, 0.28 or smaller dot pitch; display card which supports 1024x768 resolution at 70 MHz or faster.

Video
64 or 128 bit PCI interface SVGA controller. Should come with 2MB Windows RAM (WRAM) or Video RAM (VRAM), and be expandable to at least 4MB WRAM or VRAM. Recommend the selected device provide MPEG hardware acceleration.

Audio
Sound Blaster 16 or better, or compatible (only if appropriate for library setting).

Printer
Ink Jet or laser printer. Must support PostScript. 10MB Memory, minimum. More recommended if using PostScript or color.

*FOR CARTOGRAPHIC DATA USE: Color ink jet plotter, 36", 300 dip, 68 Mb or more memory, or access to a comparable networked printer

Pointing Device
Microsoft-compatible mouse or other compatible pointing device. Strongly recommend ergonomically-designed products.

Internet Connectivity
Local Area Network with TCP/IP (Strongly Recommended)
or
Dial-up SLIP/PPP connection using 33.6kbps or better Modem (Internal modem would be advisable to reduce cabling and power requirements)

Operating System
MS-DOS 6.22 with Microsoft Windows for Workgroups 3.11,
or
Microsoft Windows 95b (OEM release which includes "FAT-32" and other fixes),
or
Microsoft Windows NT 4.0 Workstation


SOFTWARE

Communications
Package which supports multiple file transfer protocols; several terminal emulations such as ANSI-BBS, TTY, VT-100. Data transfer rates up to 28.8 kbps. Supports Hayes "AT" compatible modems; manages telnet sessions. Consider ability to "script" log-on files.

Client Software
World Wide Web graphical browser with forms support. ANSI Z39.50 compatible, GILS-aware WAIS client. Consider EINet WinWais customized for GPO Access.

Viewers
WWW graphical browser (see above) will handle both GIF and JPEG graphics. Additional PDF viewer and MPEG player; consider viewers for other file formats such as TIFF.

*FOR CARTOGRAPHIC DATA USE: GEOTIFF file viewer. Viewing software for raster data, such as Photo Shop or Print Shop.

Applications Software
Consider getting an integrated "office suite" product such as Microsoft Office or Corel WordPerfect7 Suite. Otherwise:
Database
dBASE file format compatible or dBASE and ASCII comma delimited file importing database management software; useful to have fixed field format (SDF) import ability.
Spreadsheet
Lotus .WK1 file format compatible software; support for other formats such as Excel and Quattro Pro.
Word Processing
Software capable of importing major text file formats (Microsoft Word, WordPerfect, Multimate, etc.) and ASCII text files.
Mapping Software
*FOR CARTOGRAPHIC DATA USE: Data manipulation package, such as ArcView 2.1 or higher, Landview, MapInfo, or other similar packages.

Related Issues and Considerations

These specifications are intended to assist in the purchase of new public access work stations capable of using most FDLP electronic information products. Additional or different capabilities may be desirable for work stations used by library staff. Some libraries may elect to add applications software, such as spreadsheet, word processing, or data base software, to their public access work stations, but this is a local resource management decision.

Last year, LPS was advised that work stations which conformed to our specifications might not be adequate for electronic cartographic information, or to run geographic information system (GIS) software. At that time, LPS worked with the Cartographic Users Advisory Council (CUAC) to develop a supplemental set of specifications which support GIS applications. Beginning this year, additional specifications for cartographic data have been integrated into the main recommendations with the indicator *For cartographic data use.

Depository libraries are encouraged to adapt this menu of specifications to fit their local situations. Depositories may require multi-purpose single work stations, electronic access in networked environments, or a combination of both. LPS cannot anticipate or address every possible depository library computer scenario. Rather, these specifications are intended to assist depository staff in making informed purchases which will best achieve the goal of providing public access to Federal Government information in a variety of electronic formats.

Computer equipment in depository libraries must be sufficient to allow timely and equitable public access to Government electronic information products and should allow printing or downloading information selected by the user.

Given the large variation in the size of Federal depository libraries and the numbers of users served, LPS can not recommend a universal standard for the number of public access work stations in any given library. However, when assessing work station needs, librarians should consider such local factors as the amount of information provided over the Internet compared with the amount from CD-ROM, whether and how the work stations are networked, to what extent users are permitted to perform additional information processing at the public access work stations, whether users are experiencing extended waiting times at library peak service hours, etc.

LPS has deliberately not provided specifications for Apple Macintosh (Mac) or UNIX work stations. Based on responses to the 1995 Biennial Survey, Mac's are the computer of choice for a small minority of the depository libraries. However, depository libraries which have a Mac or UNIX environment should assess their functional capabilities in light of these specifications.

Many depository libraries have existing computer equipment which is no longer "state of the art." These specifications should not be applied retrospectively to existing equipment, although they may assist in determining the appropriate time for replacement or upgrading.

These specifications are not intended to describe a "best possible" work station. Instead, they are the baseline specifications which should be considered when purchasing new stand-alone public access work stations. LPS encourages the purchase of equipment which exceeds these specifications if at all economically feasible. The speed at which computer capabilities are evolving suggests that a higher initial outlay will result in an extended useful life for the equipment.
