Examine these two examples carefully to make sure you don't make the same mistakes.

Electronic documents make it increasingly easy to detect plagiarism.

Don't risk the severe penalties that come from academic misconduct, which can range from no marks at all on an assignment to explusion from the university. Groups of words taken verbatim from another source must be enclosed by quotation marks to avoid the charge of plagiarism. In the Annotated Bibliography assignment, you are limited to one short quotation that must be enclosed by quotation marks.

If you have any doubts at all about what constitutes plagiarism, take a plagiarism quiz (click on the "Practice with feedback" link).

"Chase and Koene performed this experiment to test if the mucus which covers the dart sac contains a biologically active substance. The dart sac (AKA love dart) was thought to increase the chance that the shooters sperm will fertilise the eggs. The dart sac is covered in thick mucus and is shot into its partner. When sperm enter the female tract, they travel up the spermoviduct, into the spermatecal sacs for storage until fertilization occurs. Excess sperm are transported through the bursa tract into the bursa copulatrix where they are digested. Snails were isolated for at least 10 days before testing, and placed in a small box to mate. Masses of the darts before and after shooting were taken. A photocell was placed over the organ of interest with a light source shining underneath it, and light intensity was measured when contractions occurred. They found that the mucus caused the penis, spermoviduct, genital atrium, copulatory canal and bursa tract diverticulum to contract. When the copulatory canal contracts, it closes off the entrance to the bursa tract to make the bursa tract diverticulum more accessible. This is advantageous because sperm enters through the diverticulum and is digested in the bursa copulatrix. If the opening is widened and the bursa tract is closed, then more sperm will be stored and less digested. The love dart does contain a biologically active substance, which causes more of the sperm donor's sperm to be retained, and less digested giving it a larger chance to pass its genes."

"Examining thirty two years of standardized survey catches, (1967-98) the distribution pattern for the longfin inshore squid (Loligo pealeii) provides a looking glass in which to analyze the geographic and temporal patterns of this staple of the northeastern United States' fishing economy, what are these patterns?

The longfin inshore squid is distributed along the northwest Atlantic to the Caribbean, although commercially exploited most extensively from Southern Georges Bank to Cape Hatteras.

This study took data from the Northeast Fisheries Science Center's (NEFSC) thirty years of bottom-trawl surveys. These surveys were conducted in two geographical regions 'New England' (NE) the region north of Hudson Canyon to the Gulf of Maine and 'Mid-Atlantic Bight' (MAB) the region south of Hudson Canyon to Cape Hatteras; four bottom depth zones 27-55m, 56-110m, 111-185m, and 185-366m; and time of day, night 20:00-03:59, dawn and dusk 04:00-07:59, 16:00-19:59, and day 08:00-15:59. It was found that lower catches were made at night than during daylight and dawn/dusk. There were no significant differences between autumn and winter means in MAB/NE, although it appeared that both areas were pooled by depth with the greatest catches at 111-185m in winter and 27-55m in autumn.

This study concluded the northeastern Loligo pealeii was most abundant in both the 'New England' and 'Mid-Atlantic Bight' areas at 111-185m in winter and at 27-55m in autumn."
