The Bibliometric Indicators for Publishers website presents six bibliometric indicators for publishers based on their research output and scientific impact in the last five years. Bibliographic and bibliometric is derived from Thomson Reuters’ Book Citation Index, however the publisher normalization process has been undertaken independently by the project team. Publishers were normalized manually on a one-by-one basis, improving inconsistencies detected in the publishers list provided by Thomson Reuters. For each publisher we display six indicators showing three different aspects of each publisher’s performance:

Output indicators

• PBK. Total number of books published by a given publisher in a certain field or discipline in the last five years. Minimum threshold: 5.
• PCH. Total number of book chapters published by a given publisher in a certain field or discipline in the last five years. Minimum threshold: 50.

Impact indicators

• CIT. Total number of citations received by a given publisher in a certain field or discipline at the time of the data retrieval process.
• FNCS. Field Normalized Citation Score. Normalized citations received according to the normalized indicator as defined by Moed et al. (1995).

Publisher’s profile

• AI. Activity Index. Distribution of books in a given field or discipline according to the overall output of a given publisher and in reference to the distribution of the whole Book Citation Index. If the value equals one then, the share of books as of the publisher is the same as the world average. Higher than one means more specialization in the given field.
• ED. Share of book chapters which belong to edited books from the total number of book chapters published by a given publisher in a certain field or discipline in the last five years.
