Clarifying terms

• Melvyl-T is the Transition catalog T on the name
  will be removed August 1, 2003 (http//melvyl.cdli
  b.org)
• Legacy Melvyl refers to the current CAT and PE
  catalogs, to be discontinued August 1, 2003
  (http//www.dbs.cdlib.org/)

3
Clarifying terms

• Legacy Telnet refers to the current version of
  the CAT and PE databases to be discontinued
  August 1, 2003
• New version of Telnet now on board at
  (telnet//melvyl.cdlib.org) and will continue
  indefinitely

4
Clarifying terms

• Merging records grabbing all the records for
  the same item and bringing them into one display
  or base record
• Deduping records the process of removing
  duplicate records

5
Display record

• The Display record is chosen through a very
  simple points system
• Each record in a merged group gets one point for
  every indexed heading (such as author, title, or
  subject)
• Those records with tables of contents notes (MARC
  505 fields) get an extra 3 points
• Electronic resources (856) get 5 points
• The Display record is the most complete of all of
  the records in the merged group

6
Why the heck did we do this anyway?!
7
Why we made the change

• Wanted to merge CAT PE
• Melvyls underlying technology was aging
• (not to mention aging programmers!)
• Many enhancements in web-based service delivery
  on the horizon
• New services can be delivered over time that
  wouldnt have been possible with legacy Melvyl

8
Who advised us?

• 3 teams made up of campus librarians
• Database and Technology Team
• Education and Usability Team
• Services Team
• SOPAG advised us on policy decisions along the
  way
• Evaluation Liaisons
• Many other groups also gave specialized input

9
Why were there delays in releasing the catalog?

• This was the first time Ex Libris worked on a
  project of this magnitude
• Much of the work was new development
• Logistics CDL and Data Center staff in Oakland,
  Ex Libris staff in Chicago, New York, and Israel

Why legacy Melvyl Melvyl-T search results may
differ

• Melvyl-T has clean snapshots of holdings complete
  for all UC campuses
• Melvyl-T has complete records for all the UC
  campuses and is up-to-date for UCD UCSB
• Record loading schedules are different
• Indexing is different

13
Why legacy Melvyl Melvyl-T search results may
differ

• The merging algorithm is different in the two
  catalogs
• The data is different in the two

Database Records
15
Content of the catalogs is different

• CAT and PE have been combined
• Melvyl-T contains records for UC campuses plus
  California Academy of Sciences, California
  Historical Society, GTU, Hastings, LBL CRL
• CSL records will be in by 6/30/03 (monographs and
  serials)
• Melvyl-T will not include CULP and SERHOLD

16
Why legacy Melvyl Melvyl-T search results may
differ--more on serials

• Catalogs for CSU, LLNL, Stanford and Getty will
  be accessed via links initially and eventually
  via a cross-database search engine
• These records will be more accurate up-to-date
  than in legacy Melvyl

A word about Melvyl-T Telnet

• We love it, you love it, the faculty loves it,
  but
• Telnet software creators no longer supporting it,
  e.g., NCSA
• Its a submerging technology
• Telnet protocol is a potential security
  breachrisk for the host system
• Fulltext content not available via Telnet
• Request has much more functionality via the Web

19
Telnets a little different

• Melvyl-T Telnet supports only basic search and
  display does NOT have all of legacy Telnet
  Melvyls features
• Request and Update not included in this version
  of telnet
• Records cannot be sorted as they can in the web
  version
• Once again CAT and PE are combined

20

OK, so whats new and wonderful.
21
Other new features, differences

• Circulation status for all campuses (incl. UCLA)
• Fastest searching is usually via keywords (NOT
  exact title, exact journal title, author last
  name first)
• Left-anchored true Browse (unlike legacy Melvyl)
• Use Browse for Authority recordscross refs are
  displayed here
• Search Words as Phrase

22
Use Words as Phrase to hone in...
23

24
Other new features, differences

• Truncation symbol is or ?
• Phrase/proximity searching
• Use with a number to retrieve records that
  contain terms within a number of words in any
  order, e.g., tom 5 jerry
• Use ! followed by a number for words in the same
  order, e.g., jerry !5 tom where jerry must come
  first

Handling results

• Can display in Short, Long or Review formats
• Can sort by Author/title, Title, Date (most
  recent first)

41
Records merging issuesreview

• When records are retrieved, they are merged or
  deduplicated on the fly
• There is a Display record
• Display record is decided upon by a numerical
  weighting factor which includes things like
  subject headings, if it has a ToC, if it is an
  online record

42
Records merging issues

• If 300 individual records are retrieved, there
  may only be 120 to view after they are
  de-duplicated (happens behind the scenes)
• No problem!
• However, for large retrievals, the system only
  de-duplicates enough for you to see 1,000 records
• Example subject united states civil war reports
  a search result of 30,370 individual
  recordsNOT de-duped

43
Records merging

• You can display and sort only the first 1,000
  deduped records (similar to receiving and
  displaying partial results in legacy Melvyl)

44
Records merging impacts

• Records added most recently to the database are
  the first to be retrieved
• 1,000 records displayed may not be the most
  recently publishedtheyre the most recently
  added to the database
• SO, if your result set is higher than 1,000, this
  number can not be used as a count of distinct
  titles in the database

45
Handling large search results, as all good
librarians know

• Look at some records, click on relevant subject
  headings
• Add another term to your search
• After looking at an item, use Browse to hone in
  on possible other items
• Apply optional limits
• Chunk up in time periods, e.g. 1990-2003

Truncation issue
48
Truncation Issues

• System allows you to truncate after only one
  letter
• Ex Search for (un otters) in one search box ?
  zero results
• Message is Your search term(s) found too many
  results. Please refine your search
• Try again in Advanced, search for un in one
  box, otters in the second box

49
Avoiding truncation problems
50
What are collections?

• Entire Collection
• Online Resources
• Scores
• Sound Recordings
• You can Browse within a collection

51
Caution!
Displays work best with most recent versions of
Internet Explorer or Netscape (or others) IE 5.0
and above and Netscape 6.0 and above are
recommended To display non-Roman alphabets, you
must have a font that can display the
charactersAriel Unicode MS Some older browsers
and older computers can use non-Roman character
displays, but it may be necessary to download
fonts for individual languages one at a time.
52
Caution!

• In some browsers when screen size (and hence font
  size) is much larger than the default settings,
  the entire Web page is not visible on the screen
• Result
• In Melvyl-T, horizontal scrolling is required to
  view right hand portion of the Advanced search
  screen, where the Results box is found
• Catalog users may believe their searches
  retrieved zero results if they cant see results
• Important for Melvyl-T other databases

  Print/Email, and select preview
• To save records across sessions, you must have
  first signed-in
• View each record in the Full Record format, click
  on Save Across Sessions
• Name the search folder you want to save them in

56
Saving records

• Put them in the desired folder
• To see them again, go to My Workspace
• Click on Items Saved

57
Updates My Workspace
58
Overlap period

• April 2003 August 1, 2003
• Legacy Melvyl retires as of August 1, 2003
• How will we connect to each version of the
  catalog in the interim?

Linking from UC-eLinks to Melvyl-T

• When will we start linking to Melvyl-T?
• Wanted to test initial load on Melvyl-T from
  day-to-day users
• Wanted to wait till end of the semester or
  quarter to make the changenot confuse our users
  with a new interface

61
What will it look like?
