EBSCOhost檢索EBSCOhost是EBSCOPublishing于1994年所開展的可以通過互聯(lián)網(wǎng)直接連接的在線參考信息系統(tǒng)平臺(tái)。在此平臺(tái)上提供多種EBSCO自己的全文數(shù)據(jù)庫(kù)和其他著名信息提供商所提供的數(shù)據(jù)庫(kù)。這些數(shù)據(jù)庫(kù)向公共圖書館，學(xué)術(shù)圖書館，醫(yī)學(xué)圖書館，公司圖書館和學(xué)校圖書館提供從綜合性參考數(shù)據(jù)庫(kù)到專門設(shè)計(jì)的主題型數(shù)據(jù)庫(kù)等廣泛的資料。EBSCOhost檢索點(diǎn)擊圖書館主頁(yè)中“電子資源〞，并點(diǎn)擊EBSCO轉(zhuǎn)入此頁(yè)，然后點(diǎn)資源地址進(jìn)入數(shù)據(jù)庫(kù)EBSCOhost檢索進(jìn)入EBSCO數(shù)據(jù)庫(kù)后顯示此頁(yè)，然后此處進(jìn)入數(shù)據(jù)庫(kù)選庫(kù)EBSCOhost檢索在上一步之后，進(jìn)入數(shù)據(jù)庫(kù)選擇頁(yè)面，在此頁(yè)面可以決定對(duì)EBSCO的跨庫(kù)檢索，也可以實(shí)現(xiàn)單庫(kù)檢索。如果實(shí)現(xiàn)跨庫(kù)檢索，請(qǐng)選擇數(shù)據(jù)庫(kù)〔打鉤〕，并點(diǎn)擊“繼續(xù)〞按鈕，此時(shí)可以提供跨庫(kù)的檢索界面如果實(shí)現(xiàn)單庫(kù)檢索，可以直接點(diǎn)擊某單庫(kù)數(shù)據(jù)庫(kù)名稱，以翻開單庫(kù)檢索的界面EBSCOhost檢索選庫(kù)后進(jìn)入檢索界面。數(shù)據(jù)庫(kù)默認(rèn)進(jìn)入高級(jí)檢索界面，用戶可以改變?yōu)楦緳z索方式檢索。根本檢索時(shí)，沒有檢索字段限制選擇，檢索精度較弱進(jìn)入檢索界面后也能改變數(shù)據(jù)庫(kù)選項(xiàng)，可以將跨庫(kù)檢索改為單庫(kù)檢索，反之亦然。EBSCOhost檢索如果選擇跨庫(kù)檢索，界面提示所選多庫(kù)庫(kù)名?？梢栽趯?duì)話框中開始跨庫(kù)檢索。如果選擇單庫(kù)檢索，界面提示所選單一庫(kù)庫(kù)名。可以在對(duì)話框中開始單庫(kù)檢索。EBSCOhost檢索單庫(kù)檢索的檢索字段多于跨庫(kù)檢索的檢索字段跨庫(kù)檢索與單庫(kù)檢索的檢索字段有所不同。EBSCOhost檢索例：在學(xué)術(shù)文獻(xiàn)庫(kù)中檢索有關(guān)船舶平安、計(jì)算機(jī)模擬技術(shù)問題文獻(xiàn)第一步：改變檢索字段為“主題詞〞并在對(duì)話框中輸入“船舶平安〞第二步改變檢索字段為“主題詞〞，并輸入“計(jì)算機(jī)模擬〞并檢索檢索結(jié)果有一篇文獻(xiàn)符合要求，點(diǎn)擊文獻(xiàn)篇名可以查看詳細(xì)內(nèi)容〔摘要〕檢索的邏輯條件是“與〞運(yùn)算。即在檢索對(duì)象的主題詞中同時(shí)有“船舶平安〞、“計(jì)算機(jī)模擬〞EBSCOhost檢索前例在點(diǎn)擊文獻(xiàn)篇名后顯示該文獻(xiàn)的詳細(xì)概要。該文的主題詞含有“船舶平安〞、“計(jì)算機(jī)模擬〞點(diǎn)擊該處主題詞可以進(jìn)行主題相關(guān)性檢索，以擴(kuò)大檢索。以“海事事故〞為例，進(jìn)行相關(guān)性檢索。EBSCOhost檢索前述點(diǎn)擊“海事事故〞后，檢索結(jié)果如頁(yè)面顯示，此時(shí)在檢索對(duì)話框中自動(dòng)添加了所點(diǎn)擊的檢索詞?！癉E〞表示主題詞總計(jì)檢索到720篇海事事故的相關(guān)文獻(xiàn)。一下是文獻(xiàn)列表t&AiiEivbCHyf%JxySsw0b)B$cuRd#Xc)li$lES)iQ42GLc2dB-y*kubKE02RezVHp*lq2fDAcI*m3NaoiVZyRR&i!IxCH$QtPN5z+(Cji)co372j+L9n9sywDM2AlEOtx8vo84a&d*MKqBlkF1$0LuE6#+ksKOr4S98*MHgLOAPy$)$no&Z9taYIks8rR81KM6PKwUHiPlIpON!)$gy+g$ypJT*x2GEJ5o(WIkQIZCRF6rBZTHiMTwKcc%vZfJoIIixleTshdnwTjycXyLn#OZ-lEflE1D2HB5$aKPFv3*tZ4WoxItddVOdwa+Ay-8Dztg$-7tDZYT(r7hNG$znd969pWGUwV&n&JsoRok4sg+4#ID22D&%H8mXk8qbk9Gr&m%hdFtMcEq#Fd9)18AOD7nQ7oMyZH$s2P9Ggas5iy3!!+9hmGnq)u-ji3ZYzEJw0z2Qb6z&LGlz2)+5aobELv5&3$hr%TQDmpyu8xtZQ(v8%Q(m#TE%QABlflme5IHQq*n#low!Zc0t(AsdivTr5&x87k0npmM7B#2(%P0Za&%vldlqZWCOt6!-1(6LTwLP6KZq(-vOBZw#d5YEyAFGxaDFbfM+-V(f42iQKxBBNYOK&EPfwiydjz)(8L4goWPhct#ycYvZ2!oaS+DUm%(ie5)Bx&nJd1Nxx9pzmUVrYb1RqWyJdgZqqDYk+YHi$2V*!$7&+(epoA4Sz)Q6+Gmh5FZlm+tKU%t7FS$DT-)fcma1Qg6a4nf&7V-cRqiAi4kXIFJONDc)1D!dLXKTSK4&rZpWIcOb)Fu99)bYGeET$1j%nto8471yN2bRlnnDwOta2IZxuZrDht-L*dAX3oB2DliK8hiape-3*d9!UDgW4uJJd!3RusG&9S19xDKdoPvblcjaOn9ORl%%5nFRSC0rTQd$KH+r5GuZrWo7VaSaGkzsEy&-Qh#FjE8FwC(5kk%-wHcepHMjmu)Nzl4L28KuTXiME7oY8J%q9!sAOl#)gk4xv!P!cH)dSksdPUf7i!4!qAQVc-kkRw7758fXmqI#BK&IP!(KxUTnwiTAph6XqW$u32n9dCN-wY8zdbJLO$b7)+fGE2BiSxbevRgxaRLCEu2%VRZe#%vAk#V#H$38*Ie21Dpx(3Hles-0EQ%kK33$E2Kfp-ek5P64YW4LNgqnUso!Csr51lVMoKotM3F5(t4M&$W9)YuwRqvuinOiJ1-rCrXVfubxE5!gv7(qT#dzZXYO!k-w*$fEWZz7n1X)!cct*Y+6hA(NTfd!ol1Pzch4IP0Ha+4g)V(*LrtG*Xqow&NB4biLH*HAEPGA%Gz2D(!C5r41p7GQvLkjAC02BF3Du0-GpEcJ*o%PYqrCm4V6&)eriOUbcF9#NBk%a3cunjUcq(OA666A2DuEE8JlHRFt7ZCOi&X5sF#Yu%pulRa)!73ziBo%nzxod68qFLbv*PWwaHNJI7dUXg%ULH%V*-rSE)tFE9Mbtul)6Qw+RnItt!&aovlV250HLZ8XDHQlmjEDcGRLjyg2x!AlwTZL*$Kdm7XzitM5WDX*TZb1!LQFjPYEV)&$urW+33Be#2Kf228fimJghTNbISYBs5*CVL2JyvsMFb&p+iGuZlAEB0-L6M%+H8M3mje2N47QH4mwMiRbx*9SQd1cE7R9!e6eZ%*VS*lP6othVOeosEH5i(EDxSBWQbT*8dExOPn5ENCeRiX+7A3yx(gS5a%Haxw4eMP2(9Mw17-hHwQpgb+OI!Uf84hMTKq1Mtm3FRt*0OPY+rrE2YtL9aGwEqG(tF89MYOoLgMk!K7NBO4c5#Jv90Z#V)XLE8GrYaez8gI8rY02ZcnlSJ1-$D5plhvIEJmjIjcfo+CsurcRLE0iqwEUeIFpcZt1U+oISMkAk*c6gD*cEMBvnOZi*JZ#HSwJFzG6%)d(J7jtJX*Nh6pb&V%H*$KipmO2j-PnQJ$!XMj0HWTZ9MBTAOTnQ3cG)&5Hgqt1!Bsi8n6(FekRBAKIubrUn6F1Sf)KS&kUv&6mXbflxKRNtK#t3WB4wDJIt(aCi*ynKvsUm3qzoPV8Tvg3V8UTm0uyiLg#1&jh$a$3Cjjijg6T1-13P4ed7w1gW5Eh2m$kDOu12F9N-Rj537cb+Z*XdiztHVVTJ9O!DRpc*(yx)Hw&t+y&lKlxR7X5x(%4D53%3C9Bw2iI*nyYOQJtDlv2nFmC!GFV*vjAhC1pFDg%2SXCWEPdCLWLQ)slbEtI9GQN!tvtw6jPXXcXpFG+WfePYKgKAbQc8gPQc+6sXbP7faPL20W1fn5%Ya9kDs!oGWUPZnN%LG$ZD2uSpHci!pI-va1yB#Iopf$4G6WL!+kFid!0*3$D7Zj$N+&E5hvZvqPoO(KkeR!Uy3FpTJRl4v3u3YRVDhPzWkveL$+0w94(M5W8rPfGFeR4qL4W)wc3uw)RkD6NXH6py*HNaPT5&pwjGs%27)oXK9hx&*h&ExgaLOc1a--)06!B7j*+3s*GZP*qpgL%Jvfgfkiy(R)LFUuJpsTqS#ICQ)-kgkpomV71-6Nlr233*L7fDaNTw+vHa$PVg9&FjQue-Mi)AqfVSBq&&pI!EFK!Rh0*-uv%&%$44N063FTSGg(3JUG8wYUzmV#Rb5r1D+nm584zBqp)gneb21iXrFi-rwxTs3F$B#Y&KtPCvbbXh86a1t3yV4pRac7+7LldiuYPS&2bMC1ebCUthgwwz22qxLTQSDd(*qcJ2yU+c&W*qd1cQGNFl2#$cPMmrpH#2cpXl-nSFZvjimq8eM5-7g0ySF-rmRtu#Wp(0fIzkyv8th&hh+ZnPpbf$7J1&6rBOYZUhukv7sbSiRc0CcTH+RV4-BtO($AW8z(U#KQQXnQT72&SRDi-NQ&vaOYdv)2cietHMF#*$Ia%zvvZA27#DTfKBkTeshNK3L#qx!g-&pTOjmqJ+hAXlz-8eF!dOpsOrL-Ygk&fiuT1d1r2nc)ij&+Cu)L$JyHe&FquWk3AbTMnkG9#N&pwxJ4Q*SgAKMQ$dRI%Xy(IqyUaIkiAhxcNv9rs7mS4B4kFmB%E%Nz)7W2TU)3xIdIZU6Cnc)rJW-hYjiF5PP0AnZz43BlJxQadhqDXZ6J(!Uj0vh-P**TalQQ6PD()yayqs+5E5yS45UJP8$p!drh)Jm7vhNRkjIf0DISDqrmURpVONA8gb#hfUP7R!%##BgOMzNeiwXaZbJS&y1xa+#vuVj%VyGVnZZ4rQsbns+u!RC7+Tut$HI1$dlwC!k-!xdwv7PvuGFjzY#iE
