The purpose of this paper was to examine the presence of scholarly book publishers on Twitter, and tweets about books in 10 SSH disciplines (2014–2018). This included time of tweet relative to the book's publication date and time span of twitter activity. We also investigated the ‘categories of conversation' in publisher tweets, with a focus on hashtags and @-mentions. Data collection involved matching 15,454 unique book titles from the BKCI-Web of Science with tweets retrieved from Altmetrics.com, using ISBNs. This led to a working dataset of n = 6258 books (41%), which had received at least one tweet. Our analyses show that scholarly publishers have been using Twitter more and more over a 5 year period, especially commerical publishers. Commercial publishers are more likely than university presses to have multiple Twitter accounts. Both, though mainly commercial publishers, are active at targeting the Twitter accounts of book authors, book editors, other individuals and universities/institutions/organisations. Whilst re-tweets do not often follow first, or ‘initiator' tweets made by publishers, publisher engagement in general corresponds significantly with other tweets, and contributes to keeping the book active for a longer period on Twitter. Publishers play a key role as promotional agents, particularly when a scholarly title is part of a special offer, relevant to a conference, event or special calendar date, when an author is a prize winner, or if author-agreements have been made in regards to open access book chapters.

本文的目的是研究Twitter上学术书籍出版商的存在，以及有关10个SSH学科中的书籍的推文（2014-2018年）。这包括相对于该书的出版日期的推文时间和推特活动的时间跨度。我们还研究了发布者推文中的“会话类别”，重点关注标签和@提及。数据收集涉及使用ISBN将来自BKCI-Web of Science的15,454个独特的书名与从Altmetrics.com检索到的推文进行匹配。这导致n的有效数据集 = 6258本书（41％），至少收到了一条推文。我们的分析表明，在过去的5年中，学术出版商越来越多地使用Twitter，尤其是商业出版商。商业出版商比大学出版社更有可能拥有多个Twitter帐户。两者，尽管主要是商业出版商，都积极针对图书作者，图书编辑，其他个人以及大学/机构/组织的Twitter帐户。虽然重新推文通常不会紧随其后，或者发行人发起“发起人”推文，但总的来说，发行人的参与度与其他推文有着显着的对应关系，并有助于保持该书在Twitter上的活跃时间更长。发布商在充当促销代理方面发挥着关键作用，尤其是当学术标题是与会议相关的特别优惠的一部分时，
