We present two rare cases of carcinosarcoma of the ovary treated successfully with paclitaxel and carboplatin therapy. Case 1: A 79-year-old Japanese woman was diagnosed with carcinosarcoma of the ovary stage IV. We administered neoadjuvant chemotherapy (paclitaxel 180 mg/m2 and carboplatin AUC 6). After three cycles, she underwent a bilateral salpingo-oophorectomy, hysterectomy and omentectomy as a debulking procedure. She received another three cycles of paclitaxel and carboplatin therapy as adjuvant therapy. She is well without evidence of disease 6 months after the sixth chemotherapy cycle. Case 2: A 74-year-old Japanese woman was diagnosed with carcinosarcoma of the ovary stage IIIc. We performed hysterectomy, bilateral salpingo-oophorectomy, partial resection of small intestine, pelvic lymphadenectomy, omentectomy and low anterior resection of the rectosigmoid colon as the primary debulking surgery. She received six cycles of paclitaxel and carboplatin therapy as adjuvant therapy. She has been recurrence free for 6 years. The standard chemotherapy for ovarian carcinosarcoma is not established, but we think that paclitaxel and carboplatin therapy for progressive ovarian carcinosarcoma as an adjuvant therapy might become a standard chemotherapy if further cases of ovarian carcinosarcoma treated with paclitaxel and carboplatin therapy are reported.

Librarians of Tohoku University, who produce information retrieval manuals, published their first for freshmen in 2003, revised the first as a basic edition in 2004, and published an STM Edition in 2005. They develop information literacy instruction at Tohoku University via publishing manuals and train new librarians through writing and editing. They now have started a venture in open source manuals for other libraries. This open source venture is the first of its kind at Japanese libraries. For publishing manuals, they created an information literacy course for over 100 students in 2004 consisting of information retrieval instructions and writing instructions. In information retrieval instructions, students learned through lectures and practice using online services such as OPAC and online databases, e-journals, and online reference books. In writing instructions, they learned through the lectures of a noted writer at Tohoku University.

学術情報センターでは，平成10年4月から総合目録データベースをWWWで一般に公開するサービス「Webcat」を開始した。公開の対象となっているデータベースは，学術情報センターの目録所在情報サービスNACSIS-CATにより構築されたもので，主に全国の大学図書館の蔵書のデータベースである。この総合目録データベースは，従来からNACSIS-IRという情報検索サービスや，学術雑誌総合目録（冊子体およびCD-ROM）を通じて公開されており，研究活動に必要な文献入手のためのツールとして実績がある。しかし，従来のサービスは，主な利用対象を図書館員や研究者と想定しており，学生をはじめとする一般利用者が簡単に利用することはできなかった。Webcatは，利用者を特定せず，簡便な検索方法を提供し，無料で24時間検索が可能である。学術情報センターの事業活動を広報する手段として期待されている新サービスである。
