Note: Catalogers will continue to follow national guidelines and accepted practice for recording alternate titles in fields 246 and 247.  The guidelines below address only our local, Columbia practice in assigning first indicators in those fields when cataloging electronic resources.

The general principle to be applied is that an alternate title that would be likely to sort next to or quite near the corresponding title proper in the LWeb eresource listings should be coded so that it will not generate an "added entry."  (Such alternate titles will however continue to be extracted and indexed for online searching.)  Significant variants that would be likely to sort some distance away from the title proper should be coded with 246/247 first indicator set to "1".   The guidelines below serve to illustrate the application of this principle; they are not intended to cover all cases.

Note that selectors may sometimes request that a commonly-used version of a title be coded to appear in the LWEB listings even though the guidelines below would seem to exclude it.  In such cases, the variant title's first indicator should also be set to "1".

Set 246/247 First Indicator to "0" in any of the following cases:

1. the alternate title is identical to the title proper except that it has the spelled out form of a symbol or abbreviation, e.g.,
   
   245 00 |a Accounting & tax |h [electronic resource].
   246 0_ |a Accounting and tax
   
   
2. the alternate title is identical to the title proper except that it has different word spacing or boundaries, e.g.,
   
   245 00 |a AgeLine |h [electronic resource].
   246 0_ |a Age line
   
   
3. the alternate title varies from the title proper only after the first few significant letters or words, e.g.,
   
   245 00 |a Biography and genealogy master index |h [electronic resource].
   246 03 |a Biography and genealogy master index online
   
   
4. the variant appears only in the HTML source code, e.g.,
   
   245 10 |a Civil engineering database |h [electronic resource] / |c ASCE, American Society of Civil Engineers.
   246 0_ |i HTML source code title: |a Search ASCE's civil engineering database
   
   
5. the variant is present only as an alternate spelling of another variant, e.g.,
   
   245 00 |a AccessScience @ McGraw-Hill |h [electronic resource] : |b the online encyclopedia of science & technology.
   246 10 |a Online encyclopedia of science & technology
   246 0_ |a Online encyclopedia of science and technology
