Their chronological changes are also shown. The sample comprised 10,866 OA books, which were available through the DOAB as of February 24, 2018. The results show that OA books are increasing in number at an accelerating rate. As for distribution of subjects, Social Sciences (“H” in the Library of Congress Classification [LCC] codes), Science (“Q” in LCC) and World History and History of Europe, Asia, Africa, Australia, New Zealand, etc. (“D” in LCC) are the most popular. As for languages, English, French, and German are the most popular. As for publishers, Frontiers Media SA, Presses universitaires de Rennes, and ANU Press are the most popular. Many books are newly published ones, but older books, published in or before 1999, also began to be available recently. As for the licensing patterns, “CC by-nc-nd” and “CC by” are the most popular. Considering these tendencies, libraries should begin to utilize OA books.","subitem_description_type":"Abstract"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"© Academic Research Journals"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.14662/IJALIS2018.031","subitem_relation_type_select":"DOI"}}]},"item_5_relation_37":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.academicresearchjournals.org/IJALIS/Index.htm"}]}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2360-7858","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"TSUJI, Keita"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-07-23"}],"displaytype":"detail","filename":"IJALIS_6(4)-86.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"IJALIS_6(4)-86","url":"https://tsukuba.repo.nii.ac.jp/record/47582/files/IJALIS_6(4)-86.pdf"},"version_id":"cdb6a1ce-bdc6-42b5-928d-d8b6d7949b05"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Open Access Books","subitem_subject_scheme":"Other"},{"subitem_subject":"OA books","subitem_subject_scheme":"Other"},{"subitem_subject":"OA monographs","subitem_subject_scheme":"Other"},{"subitem_subject":"Directory of Open Access Books","subitem_subject_scheme":"Other"},{"subitem_subject":"DOAB","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Statistics on Open Access Books Available through the Directory of Open Access Books","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Statistics on Open Access Books Available through the Directory of Open Access Books"}]},"item_type_id":"5","owner":"1","path":["1005","2929"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-07-23"},"publish_date":"2018-07-23","publish_status":"0","recid":"47582","relation_version_is_last":true,"title":["Statistics on Open Access Books Available through the Directory of Open Access Books"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T09:19:38.633448+00:00"}
