E-journals: their use, value and impact Key findings E-journals are a big deal E-journals are the life-blood of UK research institutions It is now estimated that 96.1 per cent of journal titles in science, technology and medicine are available online Nearly everything made available is used Information seeking is fast and direct – researchers use gateway sites Usage is rising and cost-per-use is falling High levels of expenditure are associated with high levels of use - Research Information Network
Who use a library in 2010? Everything should be on the internet.
Make a search engine where I can search for keywords in all the databases/e-‐journals available instead of having to go through every database/journal with one search word
The digital library is extremely useful
Because we are doing projects and the most quick and effecBve way is to get informaBon is to search on the internet.
I mostly use e-‐journals
An improved search engine on the papers we have access to through chalmers library
Help you to know more about different databases. Difficult to know which ones to use.
I mainly use the e-‐journal/e-‐book resources, which i find excellent. However, the search func2ons are not great, so I usually locate ar2cles using google and
use the library proxy to access them.
To be able to search the database! ... Which searches all the good databases that you have on your site. But on the same 2me! … It is also good when you cant
specify which area your ”thing” is located in.
Easier access to published technical reports (I found them very hard to find through the library web page and eventually turned to google instead).

Expenditure on print and electronic resources at Chalmers Library 1992 - 2011
“During the recession there was a reduc2on in cost for most commodi2es and goods—with the Consumer Price Index (CPI) dropping in 2009 and only increasing 1.6 percent in 2010. During that same period, serials prices con2nued to rise at well above the CPI (four to five percent), and, against the backdrop of decreased funding for libraries, price increases are very hard to sustain. Libraries do not have the resources to con2nue to exist in a world of ever-‐increasing prices, nor can publishers exist in world of no revenue increases.”

Samling?
“EN övergripande mål för förvärvsarbetet är aN resurserna kan integreras och göras sökbara. DeNa sker yNerst genom synliggörande i bibliotekets Discoverytjänst och kräver aN meta-‐data om de individuella resurserna är 2llgängligt i form av MARC-‐poster, annan maskinellt hanterbar meta-‐data eller finns representerade i en central samkatalog/knowledgebase. Utvecklingen av antalet 2llgängliga elektroniska informa2onsresurser gör det idag möjligt aN definiera stora mängder av informa2on som en del av Chalmers bestånd utan aN Chalmers har licensierad 2llgång eller har äganderäN. Chalmers bibliotek strävar emer aN 2llgängliggöra informa2onsresurser som är relevanta för Chalmers forskning, utbildning och samverkan och som är Open Access eller finns 2llgänglig i Public Domain (t ex CC0-‐licens). …
I första hand arbetar vi med aN iden2fiera och 2llgängliggöra samlingar av friN 2llgängligt material före individuellt förvärv av fria resurser. I undantagsfall inkorporerar vi individuella fria resurser 2ll Chalmers bestånd. Då vi strävar emer aN iden2fiera och inkorporera samlingar av Open Access/Public Domain-‐resurser kan det medföra aN informa2onsresurser som ligger utanför Chalmers ämnesområden blir en del av bibliotekets bestånd. … Förvärv vid Chalmers bibliotek är användarstyrt. Resurser som emerfrågas av personal eller studerande vid Chalmers ges stor vikt. Då biblioteket bedriver riktad ämnesbevakning i mindre omfaNning emersträvas relevanta pake2nköp av 2tlar direkt från förlag. Genom pake2nköp och konsor2eköp av 2tlar kan beståndet av e-‐media bli ämnesmässigt bredare än vad som skulle bli följden av eN individuellt urval av e-‐publika2oner.

Disc0very
“The Web, they say, is leaving the era of search and entering one of discovery. What’s the difference? Search is what you do when you’re looking for something. Discovery is when something wonderful that you didn’t know existed, or didn’t know how to ask for, finds you.”
-‐ Jeffrey M. O’Brien, “The race to create a ’smart’ Google”

Termen databrunn har vi tagit 2ll oss från danskans databrönd, då man i Danmark sedan 2007 har arbetat med frågan om aN samla metadata för bland annat e-‐ar2klar, e-‐2dskrimer och e-‐böcker från olika informa2onsleverantörer på eN ställe. Det ger möjlighet aN indexera datat och erbjuda en samlad sökingång för många typer av resurser, snabba sökningar, relevansrankning, klustring av sökresultat, sammanslagen träfflista etc.

Web Scale Discovery Services These services are capable of searching quickly and seamlessly across a vast range of local and remote content and providing relevancy ranked results in the type of intui2ve interface that today’s informa2on seekers expect
-‐ Jason Vaughan, Web Scale Discovery Services

“Web scale discovery can be considered a service capable of searching across a vast range of pre-‐harvested and indexed content quickly and seamlessly. Web scale discovery services provide discovery and delivery services that omen have the following traits”
Web Scale Discovery Services – Jason Vaughan
Content Harvest content from local and remotely hosted repositories and create a vastly comprehensive centralized index – to the ar2cle level – based on a normalized schema across content types, well suited for rapid search and retrieval of results ranked by relevancy. Content is enabled through the harves2ng of local library resources, combined with brokered agreements with publishers and aggregators allowing access to their metadata and/or full-‐text content for indexing purposes.
Content
Discovery A single search box providing a Google-‐like search experience (as well as advanced searching capabili2es)
Delivery These services provide quick results ranked by relevancy in a modern interface offering func2onality and design cues intui2ve to and expected by today’s users (such as faceted naviga2on to drill down to more specific results).
Flexibility These services are agnos2c to underlying systems, whether hosted by the library of hosted remotely by content providers. These services are open compared to tradi2onal library systems and allow a library greater la2tude to customize the services and make the service their own.
