Polyteknisk Boghandel
har gennem mere end 50 år været studieboghandlen på DTU og en af Danmarks førende specialister i faglitteratur.
Vi lagerfører et bredt udvalg af bøger, ikke bare inden for videnskab og teknik, men også f.eks. ledelse, IT og meget andet.
Fysisk eller digital bog?
Ud over trykte bøger tilbyder vi tre forskellige typer af digitale bøger:
Vital Source Bookshelf: En velfungerende ebogsplatform, hvor bogen downloades til din computer og/eller mobile enhed.
Du skal bruge den gratis Bookshelf software til at læse læse bøgerne - der er indbygget gode værktøjer til f.eks. søgning, overstregning, notetagning mv. I langt de fleste tilfælde vil du samtidig have en sideløbende 1825 dages online adgang. Læs mere om Vital Source bøger
Levering: I forbindelse med købet opretter du et login. Når du har installeret Bookshelf softwaren, logger du blot ind og din bog downloades automatisk.
Adobe ebog: Dette er Adobe DRM ebøger som downloades til din lokale computer eller mobil enhed.
For at læse bøgerne kræves særlig software, som understøtter denne type. Softwaren er gratis, men du bør sikre at du har rettigheder til installere software på den maskine du påtænker at anvende den på. Læs mere om Adobe DRM bøger
Levering: Et download link sendes pr email umiddelbart efter købet.
Ibog: Dette er en online bog som kan læses på udgiverens website.
Der kræves ikke særlig software, bogen læses i en almindelig browser.
Levering: Vores medarbejder sender dig en adgangsnøgle pr email.
Vi gør opmærksom på at der ikke er retur/fortrydelsesret på digitale varer.
