=Statistical Summary=
A MARS 2.0 Statistical Summary is generated for every project that involves processing bibliographic records for authority control. The Statistical Summary includes both high-level and detailed statistical information about the records processed. It also includes the number of times selected actions were taken and the number of headings that met certain criteria.

==Five Sections==
The statistical information is divided into five sections:
===Section 1: Record Overview===
A high-level view of the processed files. This section includes the number of bibliographic records by type (books, serials, etc.) and how many records were changed during MARS 2.0 processing.
===Section 2: Field Distribution===
A statistical analysis of the distribution of fields (by tag) within the bibliographic file. Included are how many records had none, one, or two instances of each field, and how many fields changed (by tag). Changes listed in this section correspond with Step 2 of the Planning Guide.
===Section 3: Authority Control===
Provides match-rate statistics for fields under authority control examined during Step 3 of the Planning Guide.
===Section 4: Authority Control Processing===
Counts of specific changes made, and conditions found, during Step 3 of the Planning Guide.
===Section 5: MARC Update Processing===
Counts of specific changes made, and conditions found, during Step 2 of the Planning Guide.

Sections 4 and 5 also serve as a list of the reports available. Those reports marked with an asterisk (following the report number) are available for all MARS 2.0 authority control projects at no additional cost.

==Section 1 : Record Overview==
The first section lists a breakdown of the bibliographic formats processed. These are broken down according to the value in the bibliographic record's leader, bytes 6 and 7. The Record Format Table (see below) lets you know what our system considers a Book or a Computer File, etc.

The '''Number of Records''' column contains the different formats that your bibliographic file comprises. The next column to the right, '''Percent of File''' directly relates to the '''Number of Records'''.

		+	==Section 4 : Authority Control Processing==
		+	This section lists all of the reports that were ''generated'' during the '''Authority Control''' processing (Step 3). Most of these are not delivered back to the client unless the client has requested that they should be. The reason why they are usually not returned is that the majority of the reports listed in Section 4 are considered '''Optional Reports''' and are at extra cost.
		+
		+	However, the first two reports listed in Section 4, '''R05-Matched Headings''' & '''R06-Partially Matched Headings''', are considered '''Optional Reports''' but at no extra cost. Both of these reports can be rather unwieldy so, unless a client requests them, we do not typically return these either. Of course, if a client wishes to view these, we can provide them at no extra cost.
		+
		+	Even though our system contains nearly 100 reports, Section 4 may contain reports that have counts of '''zero'''. This just lets the client know that not all of the possible reports found information on which to actually report.
		+
		+	This report is broken down into different reports listing the changes made during Step 3, Authority Control processing.

 Again, it is worth noting that even though a particular field may be listed (e.g., a 9XX field) within Section 2 of the Statistical Summary, that does not necessarily mean any changes were made to that field during processing. One of the purposes of Section 2 is to list every ''possible'' bibliographic field as well as any ''actual'' changes made to that field.

	When we next look at the entry for the ISBN (020), we immediately notice that nearly all of the columns have data in there. While there are 84 records which do not have an 020 field, there are just 11 records that have only one 020 field, and a substantially larger number (447) that have at least two 020 fields in there. In fact, looking at '''Max Fields''' we can see that there is at least one record with 12 ISBN fields in there.

		+	The second section deals ''entirely'' with Step 2 of the Planning Guide, Bibliographic Validation. It lists all of the possible tags that could be affected by any changes made during the implementation of Step 2's processing.
		+
		+	At first glance, this section may be a little confusing trying to understand what each of the columns represent. Let's look at a sample part from this section:
		+	{\| border="1" cellspacing="0" cellpadding="5" align="left"
		+	\|- style="background:silver"

		+	\|}
		+	<div style=clear:both></div><br>
		+
		+	The first tag in this sample part is the LCCN (010). That next column, '''0 Fields''', lets us know that there are 269 bibs with '''no''' 010 fields. Then there are 273 bibs with '''only one''' 010 field. And there are '''zero''' bibs with ''more than one'' 010 field. So right away we can see that out of our sample of 542 records, there are 273 records which have one and only one 010 field for processing.
		+
		+	The '''Max Fields''' column lets us know how many total fields actually appear in at least one record. Since we already know there are not any records with more than one 010 field, we know that the max fields number will only be '''1'''.
		+
		+	The '''Changed Fields''' column tells us exactly how many of the 273 LCCN fields were changed in some way during the Step 2 processing. In this case, 272 of the 273 LCCN fields were modified, which gives us a '''Percent Changed''' of 99.6%. Many of these particular changes are most likely due to prefix spacing or formatting incorrect LCCN (hyphens, etc.).
		+
		+	When we next look at the entry for the ISBN (020), we immediately notice that nearly all of the columns have data in there. While there are 84 records which do not have an 020 field, there are just 11 records that have only one 020 field, and a substantially larger number (447) that have at least two 020 fields in there. In fact, looking at '''Max Fields''' we can see that there is at least one record with 12 ISBN fields in there. Since the '''Changed Fields''' is zero, there was no changes made to any of the 1,089 total 020 fields.
