Title: The Alephbased Gateway . . .

1
The Aleph-based Gateway . . .

What does the new way of creating the Gateway
mean for me?

2
Roadmap for our session

What is the Gateway
How is it created now
Why the way the Gateway is created is changing
What the changes mean for OPAC users
What the changes mean for catalog users

3
First, what is the Gateway

Web site that provides access to Electronic
Resources
Selective (not all electronic resources)
Mostly resources the Library pays for

4
A little background . . .

Gateway started by Doug Archer and Carole Richter
in 1997
The goal make it easy for patrons to find
library-provided electronic resources (hard to
find in the catalog)
Began as hand coded HTML pages with links to
electronic resources

5
But then . . .

As the Gateway got bigger, it got harder to add
new resources
Donna Stevenson came to the rescue
She separated the data from the presentation
Data in simple text files separate programs
that created the Gateway from the text files
This made it much easier to add new resources
to the Gateway
Recreated daily to include new resources

6
The Gateway today . . .

Currently over 4,300 resources
More than 90 are e-journals
Organized into 4 types and 46 subject categories
Many search options
One of the Libraries most used services

7
Who does what in the Gateway . . .

Selectors identify new resources to add
After purchase approved, Ben Heet or Robin Lisek
bring records into Aleph and text files and set
up access to the resource

8
Who does what . . .

Mary Lehman and Maggie Giles catalog Gateway
resources in Aleph
Mary Lehman maintains Aleph cataloging records
for Gateway resources
Ben, Robin and Mark Dehmlow in Electronic
Resources Dept. maintain access and solve
problems

9
If this works so well, why change it?

Eliminate double creation and maintenance of
records for Gateway resources (in Aleph and in
text files)
The two files are out of synch. Dont have the
same information
Make new search options possible in Aleph

10
OK, so whats the change?

Gateway resources will be created and maintained
in only Aleph
Gateway created daily -- using only information
from Aleph records

11
To make this happen . . .

Gateway information needs to be added to Aleph
records
Most will be added by Aleph global changes
Some will be done manually in Aleph
Some Gateway programs need to be modified

12
What information will need to be added to Aleph
records?

Gateway notes (595 field)
Number of simultaneous users
Can the resource be used for ILL?
Full Text status of the resource
Gateway types and subjects (695 field)
Electronic Journals -- Business
Electronic Reference -- Psychology

13
What Gateway fields display in Aleph standard
view?

ND Coverage (if not all that is available)
Funding Acknowledgment
User limitations (max. no. simultaneous users)
Special time sensitive information
Gateway type and subject e.g. Electronic
Journals -- Mathematics

14
New search options . . .

Gateway subject browse
In Web OPAC, go to Advanced search Advanced
browse search
Choose Genre term as index to browse
Enter
Electronic Journals
Electronic Indexes and Articles
Electronic Books and Texts
Electronic Reference

15
Aleph Gateway keyword search . . .

words to search and wgn Gateway type
Biochemistry and wgnelectronic journals
Gender and wgnelectronic books
Psychology and wgnelectronic indexes
words to search and wgnelectronic searches
all Gateway resources

16
Systems and Screen Design working on new ER
searches

Aleph has many options for creating new
electronic resource searches
Some may not work as expected because of
inconsistent cataloging data
Gateway data allows accurate retrieval

17
End of OPAC part . . .

Any questions before moving on to the catalog
issues?

18
What does this mean for me if I create or update
bib records?
19
Gateway data needs to be protected . . .

Once Gateway data is added to cataloging records
in Aleph, it will be important to protect it.
This means not overlaying Gateway records, and
not editing Gateway fields.

20
How do I identify a Gateway record?

All Gateway records will have
a 595 field
a 695 field
These are new MARC tags locally defined as
Gateway fields. They only occur in Gateway
records
Again -- do not overlay records with 595 or 695
fields

21
What are the Gateway fields not to edit?

246, if 9 present
362
500 Description based on
520, if 9 present
538, if 9 present

556, if 9 present
595
695
710, if 9 present
730, if 9 present
856

-- Bring records with Gateway fields requiring
editing to the attention of Mary Lehman.
22
Overlaying implications . . .

Aleph will soon be changed so that some fields
that can have Gateway data will be retained on
overlay

23
What fields will be protected?

The fields that will be protected from being
overlayed are
520
538
556
595
695
856

24
What fields will be protected?

Note three fields that may contain Gateway
information will not be protected, because they
occur so often in non-Gateway records
246
710
730

25
This means . . .

520, 538, 556, and 856 fields will be retained on
overlay, even in non-Gateway records
This will result in two 520s, 538s, etc.
When this happens, delete the duplicate field
