What’s ‘overlap analysis’?

n First launched as part of Serials Solutions in

2004

n It “shows, for each database in a library's

collection, the number of journals in that

database that are unique to that database, and

the number that are available elsewhere in the

library's collection” SerialsSolutions press release, 29th April 2004

n So it identifies duplicate journals and titles which

have identical coverage

Why would you want to do it?

n A quick way of identifying titles which are

available in more than one provider

n Identify and remove duplicate entries

n Check coverage is correct by comparing

alternative providers (i.e. Wiley and SwetsWise)

n Identifying oddities and errors

n Simple process with minimal effort required

How is it done? - 1

How is it done? – 2

How is it done? – 3 ‘Run analysis’

What do all these columns mean?

n Title unique – the number of titles only available

through that database and no other.

n Title overlap – a journal which is available in

more than one database.

n Full holding overlap – the same content is

available in more than one database

n Partial holding overlap – some of the same

content is available in more than one database

n Holding unique – title available in more than

one database but without overlapping coverage

Reviewing the situation

n We‟ve now done overlap analysis on our entire

collection

n Let‟s restrict to three databases

n Click „edit comparison list‟ and then click on

„remove‟
